Soil cover productivity of landscapes of the boreal zone of the Yenisei Siberia

The article presents the results of a complex assessment of land resources in the western part of Krasnoyarsk Krai (Prichulymye). The characteristics of the national land reserves, productivity, soil properties, their morphological and chemical properties are given depending on the landscape features of the territory. Natural and climatic conditions are diverse, which is due to the peculiarities of the geographical location at the junction of various natural zones from taiga, subtaiga to island forest-steppes and steppes. The study area is characterized by a significant diversity of relief and is located in three physical-geographical parts: most of the Central Siberian Plateau, the eastern part of the West Siberian Lowland and the foothills of the Altai-Sayan mountainous country. The assessment of soil and vegetation cover is given depending on the geographical location and its influence on the productivity and economic activities of people. Each soil zone is characterized by the complexity and diversity of the bud cover, which is associated with a complex combination of soil formation factors. The general features of soil formation conditions are: a shortened period of active biogeochemical processes; the uniqueness of the thermal regime - sharp fluctuations in temperature throughout the season, year and day; the influence of a cold, long-seasonally frozen horizon; the uniqueness of the hydrological regime, which is associated with the slowly thawing permafrost horizon; the influence of this horizon on the dynamics of nutrients in individual phases of plant development. Chernozems are the most fertile and agriculturally developed. Based on the above studies, it has been established that the possibilities of human impact on the soil are increasing every year. They are not limited only to agricultural production, but are also associated with the expansion of the area of open-pit coal mining, which means more soil will be destroyed and covered with overburden. State district power stations, plants, factories, thousands of cars and tractors emit gases, soot, dust, which to one degree or another affect soil processes. Large areas of land near construction sites, along roads, near field camps remain unused and are subject to destruction. Thus, solving problems related to soil protection and its rational use is a very urgent task.
